bi i 1 FTENT OF PASADENA, CALL'FORNIA, ASSIGNOBS TO PASADENA, CALIFORNIA, A CORPORATION F CTAS RADIATOR- Application led November 15, 1922.

To @ZZ whom t may concern Be it known that we, HERMAN J Fisnnn and ARTHUR Bnrz, citizens of the United States, residing at Pasadena, in the county 'of Los Angeles and State of California,

` the radiator, and for insuring the proper venting of the air so that adverse down drafts which might smother the Haines of the burner are avoided. Other objects will appear as the description proceeds.

The invention will be first hereinafter described in connection with the accompanyingr drawings, which constitute part of this specification, and then more specifically defined in the claims yat the end of the description.

In' the accompanying drawings, wherein similar reference characters are used to designate corresponding lparts throughout the several views Figure 1 is a front elevation of aradiator constructed substantially in accordance with this invention.

Figure 2 is an end view thereof.

Figure 3 is a. rear elevation of the same.

Figure 4 is a central vertical section through the radiator.

Figure 5 is a vertical section on the line 5-5 of Figure 4c.

Figure 6 is a vertical section on the line 6 6 of Figure 1, and

Figure 7 is a section similar to that illustrated in Figure 5 showing a modified construction of end section.

The radiator may consist of two end sections 1 and 2, an intermediate vent section 3, and any desired number of filler sections Serial No. 601,010.

4 arranged between said end sections and vent section. vAll of the sections communicate with one another near the bottom through passages 5 and near the top through passages 6, said passages being formed by interfitting collars 7 and 8, respectively. Between the passages 5 and 6, the sections are spaced apart, as at 9 in Figures 1, 3 and 1, to increase the radiating surface of the radiator. Bolts 10 are passed through all of the sections near the top and bottom thereof for fastening said sections together, said bolts being preferably arranged in the passages 5 and 6.

The end sections 1 and 2 are made alike, each havinglegs 11 for supporting the radiator above the floor. As best shown in Figure 5, the end sections have transverse passages 12 formed therein through which air may freely pass from the ends of the radiator intothe spaces 9 between said end sections and adjacent filler sections 4t. Four of said air passages 12 are shown in each end section, two being arranged side by side about midway of the height of the section, while the other two are disposed side bj.' side nearer the top of the section and in vertical alinement respectively with the lower two. Each end section is thus divided into a central column 13, a. rear column 111 and a front column 15, said columns being erally in the form of vertical cylindi-ical tubes which communicate with each other across the central portion of the radiator between the walls of the lower and upper transverse passages 12. It will be noted that` the passages 5 and 6 through which the several sections communicate with each other are arranged in the central column 13 of the end sections.

A partition 16 extending from the rear wall of each end section to the rear one of the lower pair of passages 12 cuts off the bottom of the rear column 14 from the passages 5, but the front column 15 is in communication with said passages 5 below the front one of said lower passages 12, A curved partition 17 follows the upper edge of the passages 6 and extends from one to the other of the upper pair of passages 12, so

Gli

that communication between the front and rear columns and the central column is out off at the top of the radiator. Communication between. said front and rear columns is also interrupted at the top of the radiator by a vertical partition 18 extending from the center of the curved partition 17 to the top wall of eachend section. A U-shaped partition 19 is arranged with its base extending between the upper and lower pairs of passages 12 and its arms extending upwardly about centrally of the front and rear columns 14 and 15 and terminating below the top of each end section but preferably above the curved partition 17.

lEach'of the filler sections 4 is constructed exactly like the end sections just described, except that saidiller sections do not have the legs 11 or the air intake passages 20 which are arranged in the inner faces of said end sections below the passages 5. Air may enter the filler sections indirectly from the end and vent sections and also directly via openings or intakes 40 in the bottom of said filler sections.

The intermediate vent section 3 of the radiator, as best illustrated in Figures 4 and 6, is divided into three columns corresponding to those of the end and filler sections by vertical transversely extending air passage 21 in line with the front upper and lower passages 12 in the end sections, and a partition 22. A curved partition 23 follows the upper edge of the passages 6 and extends from the passage 21 to the partition 22 thereby cutting oif communication by either of the front or rear columns 24 and 25, respectively with the central column 26 at the top of the vent section. Communication between the three columns at the bottom is also cut of by a partition 27 which extends from the bottom of the passage 21 to the rear wall of the vent section. In the rear edge of the vent section a vent opening 28 is arranged about midway of the height thereof and below said main vent opening 28, which is designed to be connected by pipe (not shown) to a chimney, there is a small auxiliary vent opening 29. The partition 22 may be of irregular form, as shown in Figure 6, and lterminated preferably opposite the horizontal median line of the main vent opening 28. An air intake 30 is formed in the base of the vent section in line with the central column 26 and below the passages 5.

A burner pipe 31 extends through the passages 5 from one end of the radiator to the other and may have a pair of jet openings -32 and 38 arranged centrally of each radiator section. The openings 32 are in the top of the burner pipe, so that the flames therefrom are projected in line with the central columns of the radiator sections, as shown in Figures 5 and 6. The jet openings 33 are in the side of the burner pipe facing the front of the radiator and are preferably arranged at about 45 degrees from the jet openings 32, so that the flames from the openings 33 are projected into the front columns of the radiator.V No jet openings are provided in the rear face of the burner pipe because it is not desirable to heat up the rear must pass to the upper portion of the radiator before entering the rear columns thereof.

In the end and ller sections the heated air rising in the central columns'between the walls of the lower pairof passages 12 strikes the base of the U-shaped partitions 19 and is carried to the outer portions of the'front columns and rear columns, and after passing along the arms of said U-shaped partitions to the tops thereof, said heated air or fumes pass down along the inner faces `of Vsaid arms of the U-shaped partition through the inner portion of each of said Yfront and rear columns to points below the upper pair of passages 12 where said fumes enter the central columns and pass up therein between said upper pair of passages 12 to the venting passages 6 to the vent section rThe provision of the U-shaped partitions 19in said end and filled sections is especially` advantageous in `the larger sizes of radiators for the extra circulation of the air or fumes around said partition retains said fumes or gases in the radiator a longer period of time, thereby the better venting of the endand iller secf tions because a draft is caused in the central column of the vent section between the walls of the passage 21 and the partition 22 Vwhich draws the spent fumes from said outer sections and prevents back pressure which might tend to smother the iiames. To further prevent back pressure originating in the vent sect-ion, the auxiliary vent passage or opening 29 is provided below the main vent passage 28 as already described. This auxiliary vent opening gives the back pressure a. chance to relieve itself rather than put the pressure against the oncoming fumes or gases which might otherwise check the flames.

A modified form of end section is illustra-ted in Figure 7, it being understood that the same construction and arrangement of airpassages may be used in filler sections if desired. In this form of the invention instead'of the Ushaped partition 19 shown in Figure 5 ay substantially Ushaped partition 34 is arranged with its base extending` between the upper pair of passages 12 and the curved partition over the passages G. It will be noted that said curved partition 35 in Figure 7 has its lower ends spaced above the walls of said upper pair of passages 12 and that the base of said U-shaped partition 34 extends through these spaces leaving'passages 36 between it and said curved partition 35 as well as passages 3T between said base of the U-shaped partition and theupper pair of passages 12. A vertical partition 38 extends from the center of the.` curved partition 35 to the top of the radiator sectionA and corresponds to the partition 18 in Figure 5f In the operation of the modified form of the invention the heated air from the burner rising in the central column is de- 'l flected by tliebase of U-shaped partition 34, which may be V-shaped as sho-wn, and passes through the passages 37 to the upper portions Vof the front and rear columns. After passing upward along the outer faces ofthe arms of said U-shaped partition to the top of the section, the heated air or fumes move downward along the inner faces of said arms and escape through the vent openings 6 to the adjacent sections via the passages 36. This modified construction is designed particularly for very large radiators in order to give the burnt gases or fumes a little freer movement `than in the other form and insuring the evacuation of said gases without congestion at the vent.

The burner pipe may be equipped with the usual air mixer 39 and valve 40, see Figures 1, 2, 3 and 4. The end section adjacent said valve is provided with a lighting opening 41 normally closed by a swiveled cover 42.

As illustrated in Figures 1, 2 and 3, a guard 43 may be supported at a short distance in front of the radiator to prevent children or other persons from accidentally coming in. contact with said radiator and being burned thereby. As shown, said guard consists of a plurality of spaced vertical rods 44 conforming substantially to the straight front edges of the radiator sections and the curved upper corners of the same. Alternate ones of said rods are preferably arranged to register with the ribbed edges of the radiator sections and extend above and partially across the tops of said sections, while the other rods may be shorter and arranged in line with the spaces `9 between the sections.

The guard is supported in position on the radiator by an upper transverse bar 45 which is rigidly fastened in any suitable manner to the vertical rods 44 and to the radiator. As shown, the ends of said bar 45 are bent inwardly to embrace the radiator and have their extremities turned down. as at 46 to engage perforated lugs 47 cast or otherwise secured to the ends of the radiator. The bent ends of the bar 45 are long enough to space the upper portion of the guard a suitable distance in front of the radiator. The lower end portion of the guard is spaced a. corresponding distance from the radiator by a lower cross bar 48 rigidly secured to the vertical rods 44 and having rebent or looped end portions to bear against the front edges of the end sections 1 and 2. The turned down extremities of the bent ends of the bar 45 may be detachably. engaged with the lugs 47 so that the guard may be readily applied to and removed from the radiator as desired.
